Abstract
Seismic behaviors of the subway stations modeled by micro-concrete and plaster in liquefied soils under strong ground motion are compared by conducting shaking table tests. More severe damage has been caused to the plaster structure than that to the micro-concrete one. From a pure time-domain point of view, model soil-structure interaction system stated in these collected signals may be ignored, damages to the structures and ground failure are generally more time-frequency dependent than time-dependent. Based on the optimal wavelet packet transform, accelerations of the two subway stations are decomposed into time-frequency domains. The results show that the liquefied soils make the fundamental frequencies of the model soil-structure systems decrease in the feature band of 0.1 ~ 3.125 Hz, and damages of the model structures are responded first to feature band of 12.5 ~ 25 Hz that includes their own fundamental frequencies. Combing time histories of pore pressure ratio around the model structure and time-frequency-amplitude of collected accelerations on the sidewall, it can be inferred that the plaster structure may damage much earlier than the micro-concrete structure. The following greater amplitudes make the plaster structure suffer more damages.
